"LNX partition is too small for the given file" on samsung-i927

I'm trying to get postmarketOS running on my samsung-i927 device, but Heimdall is insisting that the boot (LNX) partition is too small. Only the kernel is being flashed to the eMMC, I have the rest of the system flashed onto an SD card as the wiki suggests. When I run ./pmbootstrap.py flasher flash_kernel, I get the following output:

[03:51:35] (rootfs_samsung-i927) install device-samsung-i927
[03:51:43] (rootfs_samsung-i927) install postmarketos-mkinitfs
[03:51:51] (rootfs_samsung-i927) mkinitfs samsung-i927
[03:52:10] (native) flash kernel samsung-i927
[03:52:11] (native) install heimdall android-tools

I have pmbootstrap cloned to /tmp, and I am running this on a Fedora 40 Live USB. Feel free to let me know if any more details are needed. :^)

Actually, this might be an initramfs issue since the image is now larger. I'm going to try and apply the changes from https://gitlab.com/postmarketOS/pmaports/-/merge_requests/5365 to samsung-i927, and if that solves it, I'll close this issue and open up one in pmaports.

added initramfs type::support labels

The patch worked, albeit Heimdall was still freaking out with the size check even when the image was small enough, so I had to flash with it manually by passing the --skip-size-check flag. I also had to change the compression method from gzip to xz in kernel settings for it to fit.

It's still not booting; it can't find the SD card as the rootfs, I'll move over to pmaports for the rest of the issues I'm occurring.
